phone freezes and stuters

My phone is freezing and stutering all the time, it's most noticeable when i press the apps key (third on the right). I've tried several different ROMs (always wipping data,cache system) as it appeared to be a software problem but it starts right off as i'm at the initial configuration, keys are not even responding properly, when i press a key it takes about 3 to 4 seconds to respond

I'm also under the impression the phone is overheating, it's getting really hot on top back near the camera. Any suggestions of what i might try?

Are you using cyanogenmod or CM-based ROM by a chance? I've had horrible lags on it, especially on the latest nightlies. If that's the case, try something light and AOSP-based like slimkat.

I have tried slimkat, aokp, cm11 and they all seem to be getting slower everytime i flash a new rom I think this started to happen when i first attempted to do a full backup, the phone froze during the process because it was running out of memory. It was a pain to get it working again because it was sooooooooooooooo slowwwwwwwww.

Then i just booted to cwm did a full system, data, cache wipe and installed a new ROM, during the initial steps phone starts stutering, no matter what rom it is.

My guess is that there are still some files somewhere causing the problem.
